What are the methods of carbon accounting?

Carbon accounting calculates an organization's greenhouse gas (GHG) emissions using two main methodologies:


The spend-based methodology uses financial expenditure data across various categories like energy, transportation, materials, etc. to estimate emissions. This top-down approach applies emissions factors to spending data to determine a company's carbon footprint.


  • Quick and easy to implement
  • Leverages existing financial reporting


  • Less accurate
  • Limited insights for reducing emissions


The activity-based methodology is a bottom-up approach that calculates emissions based on detailed data of organizational activities and processes that produce GHGs. This provides greater accuracy but requires more effort to collect granular data.


  • More accurate carbon accounting
  • Actionable insights for emission reductions


  • More resource intensive


Some carbon accounting platforms combine both methodologies to balance accuracy and ease of use. The hybrid methodology applies the detailed activity-based approach to high-impact areas, while using the more efficient spend-based method for lower-impact activities.

Choosing the right methodology depends on your business needs, resources, and goals for sustainability reporting. As reducing emissions becomes more vital for organizations, shifting towards activity-based or hybrid methods can provide better insights to guide climate action strategies.

What is the world's most widely used carbon accounting method?

The GHG Protocol developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD) provides the most widely adopted global greenhouse gas accounting standards.

Specifically, the GHG Protocol Corporate Accounting and Reporting Standard serves as the basis for the majority of corporate carbon accounting and reporting programs globally. Some key features of this standard include:

  • Covers the accounting and reporting of 7 greenhouse gases
  • Defines direct and indirect emissions across Scopes 1, 2, and 3
  • Outlines requirements for tracking emission sources, setting organizational boundaries, managing data quality, and more
  • Provides flexibility to accommodate varying business contexts while enabling consistent measurement across companies

Since the GHG Protocol was first released in 2001, it has been integrated into numerous carbon regulations and frameworks internationally. Over 90% of Fortune 500 companies that report on sustainability utilize the GHG Protocol corporate standard.

Its widespread adoption makes the GHG Protocol the de facto carbon accounting platform for enabling consistent and credible corporate carbon reporting worldwide. Companies leveraging automated solutions like carbon accounting software should ensure alignment with the GHG Protocol methodology.
